If there is one practice that you should ensure is acceptable under Google’s editorial and technical requirements, it would be:
● Providing a link to a website that is still under construction
● Using a URL or link that doesn’t take the user to the correct landing page, such as using a link indicating “yahoo.com”, which takes people to “google.com”
● Using generic phrases when linking, such as “click this, read more”
● Promoting content that is documented and copyrighted
The correct answer would be “Promoting content that is documented and copyrighted”. This is because Google doesn’t allow for copyrighted content to be promoted, not only to protect the individual from having their work stolen but to also deter anyone from plagiarizing. If you own the copyrighted content, then you can send the copyright documentation to Google so that it can be certified for advertising.
